Fourier Transform Infrared

The development of Fourier Transform InfraRed spectroscopy (FTIR) in the early 1970s provided a quantum leap in infrared analytical capabilities. Fourier Transform Infrared Spectroscopy (FTIR) is an analytical technique used to identify organic (and in some cases inorganic) materials. FTIR has been used because of its ability to measure a number of components as well as moisture very accurately. Fourier transform infrared (FTIR) spectrometers are typically single beam instruments. During FTIR analysis, a spot on the specimen is subjected to a modulated IR beam.
